Our piezoelectric pressure sensors with IEPE amplified output are used for a variety of dynamic pressure measurements. The sensors are well suited for continuous operation in "dirty" environments, underwater, and in field test applications across long cables. Since special low-noise cable and charge amplifiers are not required, IEPE sensor systems are substantially lower in cost per channel. Because of the IEPE sensor's low impedance output, superior signal-to-noise ratio, ability to drive long low-cost coaxial cables, they are ideal for virtually all dynamic pressure applications where sensor temperatures range from -40 to +121 ° C). For higher temperature applications, charge output sensors are available for use up to +250 ° C.
Although piezoelectric pressure sensors are primarily recommended for dynamic pressure measurements, some quartz pressure sensors have long discharge time constants that extend low-frequency capability to permit static calibration and measurement of quasi-static pressures over a period of a few seconds.
Features:
1) Fast, micro-second response time;
2) Resonant frequency is large than 100 kHz;
3) Measure small pressure changes at high static pressure levels;
4) Operating temperature range from -40 to +250 centigrade
5) Rugged solid state construction withstands shock and vibration to thousands of G's;
6) IEPE amplified output for "dirty" or underwater environments can be transmitted through long, ordinary coaxial cable without loss of signal strength or an increase in noise
